a flute plays a note with a frequency of 266 hz. what is the speed of sound if the wavelength is 1.3 m? 102 m/s 205 m/s 346 m/s 692 m/s
Answer
Explanation:
Step1: Recall the wave - speed formula
The formula for the speed of a wave is $v = f\lambda$, where $v$ is the speed of the wave, $f$ is the frequency, and $\lambda$ is the wavelength.
Step2: Substitute the given values
We are given that $f = 266\ Hz$ and $\lambda=1.3\ m$. Substitute these values into the formula: $v=(266\ Hz)\times(1.3\ m)$.
Step3: Calculate the speed
$v = 266\times1.3=345.8\ m/s\approx346\ m/s$.
Answer:
C. 346 m/s
